AutoHotkey Community

Waits for a region of a window to change or stop changing by using GDI bitmap functions and MD5 hashes. Requires Windows Vista or Windows XP. Earlier versions of Windows can be supported by using PhiLho and Laszlo's binary encoding libraries, although they're much slower. Details included in the scripts.

Really nice function. Amazingly compact.

Since I know some people have asked for this, I'm surprised no one replied. I suspect it's definitely getting used though!

I was already aware of this script, but now I actually read it. Excellent stuffs!
I have a suggestion. Use DeleteDC, not ReleaseDC, for hcdc.

I see why that's necessary, updated. Thanks guys.

Thanks Titan.

The script certainly look interesting, but I cannot get it to work. I am sure it is just my incompetence. Specifically, I cannot see what the following line does

WinExist does not seem to be a function in the documentation, and hwnd is always 0x0.

An example script just measuring change in the active windows would be very good.

WinExist() is a built-in function, maybe you need to update your version of AutoHotkey. Here is a working example:


If you still can't get your script to work please post it.

Thanks a lot Titan! It works like a charm! One use of this script would be when you start an operation that takes several minutes to finish. It would then be good to be able to push a single hotkey which would monitor the entire screen (maybe even double screens ) and make a sound when the screen changes.

Thanks, I appreciate that. I originally wrote this for my game macros but then realized it could be used for other purposes such as event handling in the cases you mentioned. I believe it was a long requested feature as well.

Ive just combined this with Rolands Gui from his wincut script to make it even easier for newcomers.

I'm if correct that script waits until a region has changed or stops changing, meaning it pauses the script? How do I make it so that the script continues until the region changes? Thanks!

in the zip, the files have GPL licenses, but on your scripts webpage, it says BSD license

which is the correct license for this function?

Ive been playing with the WaitRegionStatic function because I'd like to write a hotkey which navigates a series of pages on a website and is not dependent on predetermined sleep delays (due to the variability of internet speed this is not feasible). However, I have found that the script always seems to continue before the region actually stops changing. For example, to test this function, I was watching a youtube video of a strobe light and designated a certain pixel to be monitored. Although the entire region was changing colour quite rapidly, the script continued after a few seconds, indicating that the region was static when in fact it was not. I am using windows vista as is required by this function. Any suggestions?
